F YING-MACHINE.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application filed June 8, 1912. Serial N 0. 702,431.

To all whom, it may concern:

Be it known that I, HENRY J S N K, a citizen of the United States,residing at Santa Monica, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Flying-Machine, of which thefollowing is a specification.

My invention relates to that class of flying machines which are heavierthan air, and an object thereof is to rovide. sim le and easilycontrolled actuating means or the same. v

It is also an object to providelifting, propelling and steering meansall embodied in the same actuating mechanism. 7

It is also an object to provide safety devices in conjunction with theactuating means.

In the accompanying drawing forming a part of this specification, Figure1 is a side elevation of the structure showing the pre ferred form ofthe body or car. Fig. 2 is an enlarged sectional view on the axial lineof the forward shaft. Fig. 3 is a detail section on the axis of therearwardly placed shaft.

Fig. 4 is a section on line 4.4 looking in the 1 direction of thearrows. Fig. 5 is a longitudinal section of the helix. I Fig. 6 is aplan view of the controlling mechanism. Flg. 7 is a detail of the trackrack and its operating connections.

Heretofore it has been the practice to provide lifting; propelling andsupporting mechanism for flying machines formed of independent anddistinct devices operating independently and resulting in the consequentmultiplicity of parts, and I overcome the objectionable features of suchcomplicated mechanism by combining these. elements as described morespecifically hereinafter.

In the drawings 8 represents my referred form of body member consistingo a cylindrical shell or car with tapered ends, providing an inclosurefor the motors 9 and the bearings 1011 of the operating shafts 12 and 13of the helically formed planes or propellers 14. As is shown the car orbody is provided with suitable doors and windows and a supporting floorto carry the motors and the controlling devices, and is also providedwith wheels 15 attached to its lower portion tozallow' movement on theground and support the car in a proper position when resting upon theearth.

The forward helix 14 is rigidly secured to or formed with a shaft 12extending through an elongated bearing 17 provided at its point ofbearing in the upper casing of the car with a ball and socket joint 18or other pivotal means to allow a universal movement' of the shaft withits bearing 17. The bearing 17 extends downwardly to a point below thecontrolling station and I have shown the shaft 12 connected by suitableflexible shafting 19 to the source of power 9. The lifting action of thehelixis controlled by a sleeve 20 placed at its lower end taking up thethrust on the lower end of the bearing 17.

Placed rearwardly and properly balanced with the forward helix is acooperating helix mounted rigidly on the shaft 13, inclosed in thepivoted bearin 22, said hearing being mounted in the s 0t 23 with itsopening extending in an axial direction with the car and restricting themovement of this helix to a fore and aft direction. The shaft 13 is alsoprovided with a thrust bearing 24 with-flexible shaft connections 25 tothe motor; The shaft bearings 22 are also provided with a stop 26 whichbears on the curved peri hery of the flanges 27 "forming the sides 0 theslot, and secures the hearing and receives the thrust from the helix tothe shaft bearing. Connecting the shaft bearings 12 and 13 is a rod 28pivoted at either end to the respective shafts to control the twohelixes in proper cooperative position parallel to the axial plane.

As before stated, shaft bearing 12 extends to the controlling stationand is carried in a suitable bearing through the reciprocating rack 29mounted on the table 30 and placed in operative contact with the pinion31, provided with a shaft and operating handle 32. I have shown the rack29 in the form of a segment of an are described from the center of thepivotal bearing, a movement imparted to the handle 32 will move theshaft 1n its bearing with the helix in a direction transverse to theaxis of the car. To provide for the axial movement the table 30 ismounted on a track consisting of racks 34 engaging *pinions 35 mountedon shaft 36 and operated through bevel gears 37 by a handle and shaft38.

The motion imparted to the handle 38 by an operator reciprocates thetable in an axial direction and moves the shaft bearing 13 with itsshaft and the helix in an axial direction which movement,- as alreadystated, is also imparted through the rod 28 to the rearwardly placedshaft bearing 13. Pinions 35 also act as wheel supports for the table 30and are journaled in suitable bearings 89 which are extended below theplane of the racks 34 and hold the table impinges upon its lower surfaceand it acts as a parachute to retard the downward movement and preventthe entire structure from falling should the motive power fail tooperate.

In the operation of my invention to start from the ground the helicalplanes or propellers are started in revolution in the ver tical positionand the car is lifted clear of the ground without progression in anyother than a vertical plane. After attaining the suitable height toclear buildings or other structures, the movement of the shafts in anaxial direction will cause the planes to incline and pull in the planeof the axis. When it is desired to progress in a plane or directionvarying from this, transverse movement may be imparted by means on thecontrol handle 32 and its operating connections to carry the forwardhelix out of the axial plane and deflect the car in the directioncorresponding to the side toward which the helix is tipped. Sufiicientplay is permitted in the bearings 42 of the rod 28 to allow for thistransverse movement without materially altering the proper relation ofthe rear helix.

What I claim is:

A flying machine, comprising a body member, motive power mountedtherein, a pair of helically formed propellers revolubly supported abovesaid body, shafts secured to said propellers and projecting into saidbody, ball and socket bearings supporting said propellers and theirshafts, rack tracks disposed longitudinally of said body member, a tableadapted to travel on said tracks, a transverse rack mounted on saidtable and provided with an opening adapted to engage one of said shafts,means to limit the movement of the other of said shafts, driving meansengaging said shafts connected with said motlve power, a connecting rodjoining said propeller shafts, whereby the longitudinal movement of saidtable changes the longitudinal angularity of said propellers, andmovement of the transverse rack, the transverse angularity of saidengaged shaft.

In witness that I claim the foregoing I have hereunto subscribed my namethis 28th day of May 1912.
